President Lee Myung-bak will visit the United States later this month to attend this year's U.N. General Assembly and a high-level nuclear safety meeting, the presidential office said Friday. After arriving in New York on Sept. 20, Lee will receive the World Statesman Award by the Appeal of Conscience Foundation for his contribution to world peace, democracy and human rights, the office said. Previous recipients of the award include former South Korean President Kim Dae-jung, German Prime Minister Angela Merkel, French President Nicolas Sarkozy and former British Prime Minister Gordon Brown. Lee will then have dinner with the South Korean-born, U.N. Secretary General Ban Ki-moon. On Sept. 21, Lee will deliver a keynote speech at the U.N. General Assembly where he plans to declare South Korea's commitment to play greater roles in the international community to promote international peace and stability, democracy and human rights, and sustainable development, the office said. Lee also plans to present his vision for "ecosystemic growth" calling for reducing social inequalities. On Sept. 22, Lee will address a high-level U.N. meeting on nuclear safety, stressing the importance of gaining trust in atomic energy and calling for greater international efforts to improve the safety and transparency in nuclear energy, the office said. Lee also plans to brief the participants on next year's Nuclear Security Summit in Seoul. At least two bilateral summits are scheduled for during Lee's four-day visit to the U.S. through Friday. Officials declined to discuss details, but he may meet with U.S. President Barack Obama or new Japanese Prime Minister Yoshihiko Noda. Lee will visit Seattle on Sept. 23 for a meeting with South Korean residents there before heading home the following day.
